3 Claims.

This invention relates to certain improvements in closet bowls andparticularly to a novel arrangement and method of flushing these bowls.

In the conventional bowl, there is usually a rim flush and in someinstances the rim flush is provided with an ejector jet for forcing thewater through the up leg or trap of the bowl.

It is likewise old to provide a jet entering the main part of the bowlin combination with a rim ;flush and this jet has also been tangentiallyarranged with respect to the sides of the bowl.

It is also old to provide the rim flush with slanting outlet openingsfor producing a swirling motion of the flushing water as it enters thebowl, but none of the former constructions is capable of producing thesame result, or operating on the same principle as in applicantscombination of devices.

The object of the present invention is to provide ;a bowl wherein alower jet directed upwardly through the up leg of the bowl trap, hereinreferred to as the ejector jet, cooperates with a substantiallyhorizontal vortex producing tangential jet and the rim flush, so thatfirst, the sides of the bowl are washed, then the horizontal jetdirected. against the sides of the bowl, causes a fan of water to give astill more thorough washing of the sides of the bowl. These two washescombine in a circular motion with the help'of the ejector jet to producea vortex in the bowl and a continuation of the vortex to the up leg ofthe bowl trap. A further object is to accomplish this with a singlesupply chamber from which the three water sources are diverted to theirrespective points of discharge.

A still further advantage is that by the present construction andarrangement of jets and method of operation, it is possible to provide adeeper water seal in connection with the vortex than is possible withoutthe help of the ejector jet to lift the vortex through the up leg of thebowl. For this reason a deep seal bowl can be produced and at the sametime a bowl that will operate quickly and with a smaller amount of waterthan would be possible without the combination of jets coacting in themanner described.

The preferred embodiment of the invention is illustrated in theaccompanying drawing in which Figure 1 is a plan view and Figure 2 is avertical sectional view of the improved bowl. 7 i

Referring to the drawing in detail the bowl 1 of any improved or wellknown design is provided with a rim flush 2, a bowl trap 3 and thenecessary soil connection 4'together with a supporting base 5, all ofwhich can be of the usual or conventional design.

Associated with the rear upper portion of the bowl is an inlet chamber 6to which is connected in any improved manner the water supply pipe, notshown, for flushing the bowl.

Communicating with this chamber 6 and formed preferably as an integralpart of the bowl is a water chamber '7, said chamber in turncommunicating with a passageway 8 terminating in an ejector nozzle 9.This chamber '7 also suppliesa tangential jet 10, the outlet opening ofthis jet being arranged substantially at the water line of the bowl andso formed as to direct the stream in a slightly upwardly directionbutsubstantially horizontal with respect to the water line of the bowl,this jet 10 being disposed to one side of the inner part of the bowl asshown. With this arrangement the water discharged from the jet 10 in atangential manner against the sides of the bowl causes a spreading orfanning of the water both upwardly and downwardly and at the same timeproducing a vortex or swirling action of the water in the bowl.

The ejector jet 9 above referred to is directed upwardly into the up leg11 of the bowl trap and in the actual operation of the device causes acontinuation of the vortex or swirling action of the water of the bowlin the up leg 11 of the trap.

Cooperating with the tangential jet 10 and the ejector jet 9 is the rimflush 2, so that upon the proper prcportioning of the size of these jetsand the simultaneous operation thereof, the walls of v the bowl arecompl tely flushed.

As hereinbefore stated, the combined efiect of 1c three pressure jets asshown produces a novel flushing operation not possible with anyprevious-- ly designed or constructed bowls of this general type. Thefact that the tangential jet 10 is disposed substantially at the waterline of the bowl, not only products a direct swirling or vortex actionof the water in the bowl but a portion of the water ejected is forcedaround and up the sides of the all simultaneously operated to produce avortex action in the bowl and a siphonic action in the up and down legof the bowl trap.

2. In a siphonic closet bowl, the combination with a common water supplychamber, of a rim flush, a substantially horizontal tangentiallydirected jet located approximately at the water line of the bowl and anupwardly directed ejector jet at the lower part of the up leg of thebowl trap, said jets being properly proportioned as to size with respectto each other and functioning simultaneously to produce in the bowl, acomplete wash down, a swirling action in the form of a vortex and anejection through the up leg of the bowl trap.

3. In a siphonic closet bowl, the combination with a water supplychamber formed as an integral part of the bowl, of means for supplying 7water to this chamber at the upper rear portion of the bowl, a flushingrim, a fan shaped current producing tangential jet discharging into thebowl approximately at the water line of said bowl, an upwardly directedejector jet at the lower portion of the up leg of the bowl trap, saidflushing rim and jets each communicating with said supply chamber andthe outlets from the flush rim and jets being properly proportioned asto size with respect to each other so that when functioningsimultaneously they will produce in the bowl, an exhausting of the upleg of the bowl, a pulling down of the water level therein and causing avortex action in the bowl between the simultaneously operated jets.
